Description
La présente invention concerne les cellules électro-The present invention relates to

utilisant ces matières. Le chlorure d'aluminium est particu- using these materials. Aluminum chloride is particularly
lièrement intéressant pour les accumulateurs à régime élevé. interestingly for high-speed accumulators.
Toutefoison a trouvé que les accumulateurs au lithium et au chlorure de thionyle utilisant le chlorure d'aluminium However, it has been found that lithium and thionyl chloride accumulators using aluminum chloride
étaient inacceptables dans certains cas en raison de la fai- were unacceptable in some cases because of the
ble conductance de la solution d'électrolyte et de la nature très corrosive de la solution acide, Si l'on pouvait modifier les solutions de chlorure d'aluminium dans le chlorure de thionyle de façon qu'elles présentent une conductivité améliorée,cette cellule électrolytique serait bien mieux acceptée. On a maintenant trouvé que l'on peut améliorer selon l'invention les cellules électrochimiques comportant une anode de lithium et une cathode avec un électrolyte dépolarisant formé de chlorure d'aluminium en quantité électrolytique dissous dans du chlorure de thionyle,en utilisant dans la cellule électrochimique du chlorure de gallium en quantité the conductance of the electrolyte solution and the highly corrosive nature of the acid solution, If the solutions of aluminum chloride in thionyl chloride could be modified so that they have an improved conductivity, this electrolytic cell would be much better accepted. It has now been found that electrochemical cells having a lithium anode and a cathode with a depolarizing electrolyte of electrolytically dissolved aluminum chloride dissolved in thionyl chloride can be improved according to the invention by using in the cell electrochemical quantity of gallium chloride
suffisante pour augmenter la conductivité de l'électrolyte. sufficient to increase the conductivity of the electrolyte.
Normalement,cette quantité de chlorure de gallium est d'environ 0,1 à 0,9 mole par litre de solution. De préférence, elle est d'environ 0,2 à 0,5 mole par litre de solution d'électrolyte. On a évalué un certain nombre d'autres chlorures pour déterminer l'effet des additifs sur la conductivité Normally, this amount of gallium chloride is about 0.1 to 0.9 moles per liter of solution. Preferably, it is about 0.2 to 0.5 moles per liter of electrolyte solution. A number of other chlorides have been evaluated to determine the effect of additives on the conductivity
